About roman numeral converter
Roman numerals are used on clocks, book chapters and film credits. The converter works between them and ordinary numbers from 1 to 3,999.
The symbols
- I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000.
- Smaller before larger means subtract: IV = 4, IX = 9, XL = 40, CM = 900.
- Symbols are never repeated more than three times in a row, so 3,999 (MMMCMXCIX) is the largest standard value.
Example
1994 = MCMXCIV (1000 + 900 + 90 + 4).
More examples
The year 2026 is MMXXVI (1000 + 1000 + 10 + 10 + 5 + 1). The number 49 is XLIX (40 + 9). A clock face shows I to XII, and the number 4 is usually written IV, although some clocks show IIII.
